The downhaul is a line (or rope) which is part of the rigging on a sailboat; it applies downward force on a spar or sail. The most common downhaul on a modern sailboat is attached to the spinnaker pole, although the term is also commonly applied to the Cunningham on the mainsail.

The spinnaker pole downhaul performs much the same function as a foreguy, but is not actually identical; the foreguy is attached to the outboard end of the pole, while the downhaul applies its force to the middle of the pole.

This makes it very easy to attach and detach the downhaul from the mainsail, allows the two double blocks to be suspended below the boom, where they won't catch on anything, and gives the two bullet blocks more freedom to align with the load.
Downhaul systems that have cheek blocks riveted to plates at the tack of the mainsail get pretty loaded up and can explode blocks due to loading them in weird directions.
Since the double are on a 2:1 system, you have a max potential downhaul range of 1/2 the distance between the double sheave and the swivel block.
